OK. But MSI provided the motherboards, CPUs, GPUs, PSUs, and HDDs, so why weren't all the boards loaded with the same bios before the competition started? What about OS configuration, and display drivers? Isn't everyone given the same basic setup? Is the team's ability to find the right bios, and drivers and install them correctly something they're judged on?:|

having used LN2 everyday for about 7 years I can say it burns if you leave your hand in ti for too long - but you can flick it or throw it at someones jeans quite safely! ...I've been stuck to the spot for fear of shattering my frozen trousers a number of times :-)

All the hardware is retail boxed so it stands as good a chance of arriving in good order but I guess it's easier and quicker to get each team to flash to the correct BIOS than one person doing this 15-20 times. But yes, it's unfortunate that this wasn't picked up on...

I'm not some health and safety freak, but come on, show the stuff the respect it deserves!

I've never used the stuff but I think it evaporates too quick to freeze your hand, you would have too dip your hand into it.

It's called the Leidenfrost effect. What happens is that part of the LN2 evaporates into N2 gas as soon as it touches, so there is a always layer of gas between the liquid and your hand, so it won't freeze you unless you really try to.

There's a vid on the final page :D

ooh lol my bad I thought it was another picture lol didnt catch the caption, okay let me correct wish there was a video that covered the event. not a small snippet like that. Like have one OCing session recorded from them setting up the gear to then tweaking the gear and what not.

A pot like that would be very a poor usage pot the problem is that some cpu's don't like -196c they just stop functioning with a pot with no mass at the bottom by putting ln2 in the pot it would drop way down to fast and have no load holding the pots with larger mass between the cpu are used in a different way the pot is cooled by the ln2 and the cpu is cooled by the pot but due to the large mass that is cold it stays colder longer which makes it light work :)

The pots with no mass are very hard to control but use little ln2 the larger pots like mine in the pics take more to get cold (1l for -100c) but stay colder longer say a 5c drop every 30's or so.

You could say there tuned to load the same as a single stage phase cooler would be.
